Conclusion:

This temperature / humidity sensor is a nice addition to your smart home. You can use it, for example, to control your heating, by knowing the temperature per room in a targeted manner. The humidity sensor is great to use in the bathroom to, for example, control your ventilation. You can attach it well with the included double-sided sticker. This sensor is super light, so it needs almost nothing to wear.

The small size of 3.60 x 3.60 x 0.90 cm is definitely a plus. The price is also small because it is already for sale between € 7.50 and € 20.
